How Many Databases Connected To MySql Server
I've read MySql can handle up to 60,000 tables and 500,000,000 records per database, but how many databases can I connect to 1 MySql Server?

Is There Anyway To See Ports And See What Is Connected?
Got mysql started, created root password. Decided to change it and used mysqladmin to try and change. It says access denied. I tried to stop the service, can't do that. I even restarted the computer and it says there is still a connection on localhost:3306 and it can't make changes. I have deleted mysql and completely re-installed. Nothing changes. How can I completely stop the service that it tying up :3306. Is there anyway to see those ports and see what is connected?
Two Different Websites Connected To One Database But Only One Works...
I have been recently having problems transferring my website from one domain name to another. The first domain name was used whilst at uni, but the second is my own perosnal website. One the original website, the MySQL database allows the user to login and register new users without any problems. However, the second website does not allow me to do this. I would consider myself a newbie when its comes to MySQL so I was wondering if the community could help me out on this one. Both websites are hosted by the same company, and both websites use the same database but my limited knowledge cannot solve this problem. Are there certain permissions I need to set or something? Can anyone help me out on this one?
Querying Databases On Different Server
I'm not sure if this is possible, but i have one site that is hosting the database and i am creating another site where i would like to use the database from 1st site. How would i go about doing this? Can it even be done in MySQL?
Lost Connection To MySQL Server During Query / Server Has Gone Away
All of a sudden the server stopped working. When trying to execute a simple INSERT both from PHP and Query Browser, the server crashes and I get either "Lost connection to MySQL server during query" or "Server has gone away" errors. The problem started on 5.0.18, and upgrading to 5.0.41 didn't help. I'm using Windows XP SP2. I've seen quite a few posts on similar problems, but no real solutions though. Is that a bug?
Connect From Unix Mysql Server To Ms Access Server
Im wondering is it possible to connect through my mysql db (running on fedora core 4) and access the ms access tables on the ms access server? I have a connection setup the other way around using an odbc bridge, is it possible to do this the other way around enabling me to view / edit the access tables through mysql.
SQL Server 2000 To MySQL Server
I'm trying to do an export from an SQL Server 2000 Database to and ODBC driver pointed to a mySQL Server Database. The export works if there is at least one record in the mySQL table. If the mySQL table is empty it gives an error that looks like this: Insert error, column 1 ('field1', DBTYPE_STR), status 6: Data overflow. The strange part is that the export works perfectly fine as long as there is one record in the mySQL table, if there are no records in the table, I get the error above.
Mysql Server And Regular Server
I recently decided to get another server to do just mysql, however, I ran into a few problems. As soon as I switch the script to pull from the other server it creates a huge lag between the two and eventually starts timing out the sites. in my.cnf i did do skip-name-resolve but still the same thing. Are there any programs or anything that are maybe bottlenecking it because the site will load in the first 10 secs after i switch the mysql (with a lag) but that lag gets bigger and bigger. The mysql error log doesn't show anything weird either. To further complicate things, another server that was pulling off it worked for the first few hours, then when traffic started to increase, it started doing the exact same thing. (both server loads were low and max connections was not getting even close). Roughly 600 qps, half to HEAP tables.
MySQL Databases
I've had to switch hosts and have been using Invision Power Board on the old host. When i tried to switch to the new host I discovered that they had an older version (1.2) and that everytime I tried to import the database they would return multiple errors, even if I dropped tables beforehand on the newly set up board. Can I transfer the data to this new board? Is it possible for me to just transfer the individual table information? Can I even tansfer the information to a new php-based board?
MySQL Databases
Can I look at the tables in a database on my hosts server? Like most hosts, the only access they give me is through DirectAdmin, but in the absense of a DirectAdmin forum, I guess the MySQL forum is the logical place for this post. I guess a MySQL command line would allow me to do this, unless there's a different way. How is this done?
Merge Two MySql Databases
I have two databases on my website lebphoto.com with the same tables. One with a 1665 members and the other with 33 members, I want to merge them together. is there a way other than typing each records by myself or ask the members to register again?
Dimension Databases With MySQL?
Am looking for some kind of design which would help me to hold data like a spreadsheet - as in, having columns and rows, so i can present the data as is to the client, i tried to look around for information, but am still a little unclear on how to achieve this using mySQL.
MySQL Databases And 2 Servers?
We are planning to reprogramm our search machine and website. Since we have call agents who query the same database as the customers do, we had the idea of splitting the database to 2 servers. The call agents can update customer data with our intern webinterface, which not only concerns tables that are for the call agents, but also concerns tables of the search machine, holding company data such as address, search words, etc. O.k., now my questions. Since the customer himself can administer his own data, as well as the call agent (or media agent), I was thinking of doing following: * I have 2 servers. Server 1 is responsible for the search machine and just serves customers searching for a company or for products. The MySQL database is there just for querying. * Server 2 serves call agents, as well customers who want to change their data, reading and writing. * Since the search machine should of course show updated data the call agent or the customer have eventually changed, the data from server 2 must be synchronized with the MySQL databese of server 1. (e.g. at midnight) Questions: ------------- 0. Is the above described the right way? 1. What do I have to consider when planning the database structure? 2. How do I synchronize? Can I copy specific tables from one server to another using cronjobs (crontables)? Since this is absolute newland to me, how? Any expert knowledge or experience with MySQL replication or MySQL clusters? I think replication is just thought for mirroring, or am I mistaken?

Synchronizing Two Mysql Databases
I have a MySQL database that is running on a server. If this server goes down, a backup server with the same database is automatically started. The backup database is synchronized with the first one periodically. Suppose that during the downtime of the primary server several new rows have been added to a table in the backup database. What I wish to do is merge the two databases, in such a way that no rows are lost. The problem is that the tables in both databases are the same up to a point, then the last few records are different. (in both databases, not only in one of them). I can't simply "merge" the two db files, since they are binary.... anyone got an idea about any tools that can do this?
Optimizing MySQL Databases
I bet you're about to say "Well, use the OPTIMIZE function." See, the problem is that the OPTIMIZE function isn't what I'm looking for. In all honesty, I don't even know what the OPTIMIZE function can do, but I know what it can't. Here's an example of the problem ID | Bytes | Field | ... ---+-------+-------+ 1 | 0001 | ????? | (Ignore the data) 2 | 0010 | ????? | 3 | 0011 | ????? | 5 | 0101 | ????? | <-- Here's the problem 6 | 0110 | ????? | Well, I think you get the idea. The problem is the gap in between the auto_increment value ID from row 3 to 5. What I'm wanting it do is 'compress' the rows and get rid of that little increment gap, like this: ID | Bytes | Field | ... ---+-------+-------+ 1 | 0001 | ????? | 2 | 0010 | ????? | 3 | 0011 | ????? | 4 | 0101 | ????? | <-- Here's the fixed problem 5 | 0110 | ????? | So, would anyone know any MySQL or PHP to help this out?
MySQL Databases And Usernames
Let's say I make a database called "bri" and then username "site1" Can I use the same database, but create a new username "site2" for a different site? Like, say I installed Wordpress on "site1" and vBulletin on "site2"... does that work? I've always just created a new database, but I've been wondering about this.
Differences In MySQL-databases
How come this difference? INSERT INTO `db1_search_wordlist` VALUES ('bara', '251', '0'); INSERT INTO `db2_search_wordlist` VALUES (0x3237, 3861, 0); Data from two different databases on different servers, both using phpBB. But why that difference in the database? rying to move phpBB-forums from one server/db to another, but got a few problems. Since my users mostly use nordic letters like åäö (not sure you can see those, but å can be seen when entered into HTML. An a with a ring over it...) I had to convert some chars from the db into correct HTML (å etc), otherwise the output on the new server would be some rubbish when it came to special chars. Problem is when converting, words cannot be found when doing a search with one of those special chars. And since words are entered into db as a strange string I'm unable to change it there. Could a solution for me be downloading all files related to the db and upload the needed stuff at the new server?
MS Access And MySQL Databases
I have an Access database that is used for a station computer. Now I want to update this database for a small network for about 4 computers (to share this database). I know that I can link an Access databse to a MySQL server. My question is: It is possible to use one of those for computers as a MySQL server then 4 computers will use 4 copies of this Access application to connect to the MySQL server to share data.
Uploading MySQL Databases
I need to know if anybody can help me with this: I have developed a php app with mysql database. Now I need to upload my app to be online, which I've done today. Now I need to upload the database. all the hosting companies I've consulted, say that I must CREATE the database in their servers... my problem is that I ALREADY have the database (more than 26 tables, populated with data) and don't want to CREATE it again. I don't have experience working with online databases, so I really willl appreciate if anybody can explain me if there is a way to upload an existing mysql database from a localhost to the server of a hosting company.
Synchronize Two MySQL Databases
I was wondering how to synchronize my two different MySQL Databases together. For example, when my main database get's some new info, it will be synchronized with my backup database, which is located on another server.
Looking For Mysql Test Databases
Today I added a feature to an app I wrote (SqlSpec) that allows you to generate docs about any MySQL database (5.0 or above). As I am just one guy, I need a little help testing it. Also this is my first foray into the world of MySQL. So my question is, does anyone have any scripts for large databases (that is, many, many objects) in MySQL 5.0 and up they would be willing to share? Anything of decent size would be appreciated (I don't need the data, just the script to create the objects). All I have been able to find of any substance is sakila, which isn't all that big or complex. I'd like to test it on something more meaty.

Restore Mysql Databases From /var/lib/mysql/user_database/ Files Only?
I recently had a harddrive failure and luckliy I can still access certain directories on this failed drive. I can still access the /var/lib/mysql/ directory which holds all the users databases and have backed all these up separately using tar. Now what I need to know is how do you restore these database files to another server? I tried simply untar'ing one of these to the new servers /var/lib/mysql/ direcotry and it stuffed Mysql up - it went offline. I had to get a cpanel tech to bring Mysql back online.
I Caonot Get Php To Connect Any Mysql Databases ??
Not to sure if its a php setup problem or if its mysql. <?php unset($dbfailed); if(mysql_connect("localhost","root")) { mysql_select_db("family")or $dbfailed=mysql_error(); } else { $dbfailed="Could not connect to database"; } if(isset($dbfailed)) { echo $dbfailed; } ?> I have used 'root' and no password. I have set up via mysql administrator the privileges to everything. What else do I need do ??? as that still does not work. Is it one of the setup ini files ????

I tried mysql < file.sql since for the tables counterpart it is mysql mydb < fileOfTables.sql But I couldnt get my databases out into mysql. How do I do this?
Public MySql Databases Online?
I am new to MySql and I want to practice querying by playing around a relatively large and complex database without having to enter all the data myself. Is there a publicly available MySql database on the internet which I could download? (the "world" database on the MySql website is really to simple to be useful). Of course, it would be even more pleasant if this database contained some interesting data.
Backup/Restore MySQL Databases.
Is it safe to say that restoring the [/usr/local/myql/data] directory from a backup would that restore all database data and structure? All usr/pwd and GRANT info?
Unable To Connect To MySQL Databases
I've downloaded the MySQL 4.1 package for MacOS X.3 and things seem to be running, although I did have to manually run the mysql_install_db script as it didn't seem to run properly during install. Anyhow the PrefPane keeps telling me that the database server is running but when I try to connect using XOOPS or even an SQL GUI like Cocoa MySQL I cannot connect. I can login as root using the command line: mysql -u root -p and I can create databases and drop databases and tables etc but no external app can connect such as XOOPS or Cocoa MySQL using the same login details.

Handling Very Large Databases In MySQL
Currently I have a database of about 3.5 GB which contains about 5 text fields and to enable fast accesses to search this I have to use FULL TEXT INDEXES. My server has a RAM of 3.5 GB and I need to find a way so that I can have fast search process on this database.
Restoring Mysql Databases Manually
have recently had to upgrade my sever from redhat9.3 to fedora core 4.0. Generally to back up a site I would sql dump the data base and ftp the site.. then rebuild latter.. but I didn't do it for one of the sites although I did ftp all the domains and all the mysql folders with the *.frm, *MYD .MYI. could anyone shed some light on how I would reconnect the database to the site.. (i've tried just ftp the myqsl back to it previous location)

User Names And MySQL Databases
I have just changed hosts and servers and I am trying desperately to correct my MySQL databases. My backed-up databases were under the user name, "kaitco_" and then the name of the database. I need to edit the databases so that instead of them pointing to kaitco_, they point to dorie3_, and I have no idea how to do accomplish this or if there is even something better that I should be doing.
Change Path To MySQL Databases
I have a server where the databases are currently stored in /var/lib/mysql They are out growing that partition on the hard drive and I need to move them to another partition... Let say /home/mysql How to I tell the mysql core program that the databases are to now be stored there and not in the old location?
Mysql Heavy Load On Databases And Connections?
I'm preparing for a lot of potential traffic to a web app. My question is. Is there any restriction on the amount of databases you have on a single mysql installation on a linux server. Could there be any performance issue if for example I had 100,000 databases all being connected to at different times? What is the upper limits of a standard LAMP dedicated server? What i mean is how many simultaneous connection can it handle before it starts to slow down for the users?
Installed MySQL On WinServer2003, Can't Create Databases
It installed as a service, and seemed to start just fine, but on the 'databases' tab of the WinMySQLAdmin ver 1.4, I can't create databases. It shows 'test' but no tables.
